On one outer wall of the conveying frame 3, there is a stepping motor one 5 installed for driving the chain roller feeding structure 4 to work. At the top of the cutting machine frame 1, there is a dual-axis moving module 7. The Y-axis moving end of the dual-axis moving module 7 is installed with a laser cutting head 8. On the top of the conveying frame 3 on one side of the U-shaped hopper 2, there is a longitudinal beam 6, and at the bottom end of the longitudinal beam 6, there is a receiving hopper 12 slidably installed. At the top end of the longitudinal beam 6, there is a Y-axis lead screw linear feeding module 11 for driving the receiving hopper 12 to perform Y-axis sliding. The relative ports of the receiving hopper 12 and the U-shaped hopper 2 are interconnected. On the inner wall of one side of the U-shaped hopper 2, there is a horizontal pushing component 9. The moving end of the horizontal pushing component 9 is installed with a retaining arm 10, and the lower surface of the retaining arm 10 is in contact with the bottom wall surface of the U-shaped hopper 2. The retaining arm 10 is made of a stainless steel component;

[0020] On one outer wall of the cutting machine frame 1, there is a PLC control panel 13 installed. The output end of the PLC control panel 13 is electrically connected to the input ends of the stepping motor one 5, the dual-axis moving module 7, the laser cutting head 8, the horizontal pushing component 9, and the Y-axis lead screw linear feeding module 11;

[0021] The chain roller feeding structure 4 includes a driving shaft and a driven shaft rotatably installed on both sides inside the conveying frame 3. At both ends of the surfaces of the driving shaft and the driven shaft, there are sprocket discs installed. Between two sprocket discs in the same X-axis direction, there is a chain roller installed. The output end of the stepping motor one 5 and one end of the driving shaft are connected to each other through a coupling. The chain roller feeding structure 4 can feed the metal sheet material to be cut into and out of the cutting machine, so that there is no need for staff to manually load and unload materials, and only material connection is required;

[0022] The dual-axis moving module 7 includes an X-axis lead screw linear module installed on one side of the top of the cutting machine frame 1, and a Y-axis lead screw linear module installed on the moving end of the X-axis lead screw linear module. The Y-axis lead screw linear module and the X-axis lead screw linear module are in a vertical structure. The laser cutting head 8 is installed on the moving end of the Y-axis lead screw linear module. The dual-axis moving module 7 is composed of two lead screw linear modules distributed vertically, so as to respectively control the position of the laser cutting head 8 in the X-axis and Y-axis directions, and it can effectively control the cutting path and process of the laser cutting head 8; The laser cutting head 8 can generate a laser beam with a high energy density for cutting metal materials;

[0023] The horizontal pusher assembly 9 includes a U-shaped long frame 901 installed on the inner wall of one side of the U-shaped hopper 2, and a sliding table 903 slidably installed on the surface of the U-shaped long frame 901. One end of the retaining arm 10 is fixedly connected to the outer wall of one side of the sliding table 903. A pulley translation structure 904 for driving the sliding table 903 to slide is provided at the top of the U-shaped long frame 901. A second stepping motor 902 for driving the pulley translation structure 904 to work is installed on the inner wall of one side of the U-shaped hopper 2. The rotational power of the second stepping motor 902 is transmitted to the pulley translation structure 904, and then the pulley translation structure 904 drives the sliding table 903 and the retaining arm 10 to move together in the X-axis direction. During this process, the retaining arm 10 can uniformly push the waste materials in the U-shaped hopper 2 into the receiving hopper 12;

[0024] Dovetail grooves 601 are provided on both sides of the bottom end of the longitudinal beam 6. Dovetail ribs 1201 that are slidably matched with the dovetail grooves 601 are provided at the top of the receiving hopper 12. When the Y-axis lead screw linear blanking module 11 drives the receiving hopper 12 to slide, the longitudinal beam 6 and the receiving hopper 12 are slidably matched through the dovetail grooves 601 and the dovetail ribs 1201, so as to improve the sliding stability of the receiving hopper 12 and ensure that the receiving hopper 12 can slide in or out stably.

[0025] When the embodiment of the present application is in use, first, the staff places the metal sheet to be cut and processed on the chain roller feeding structure 4, and the staff turns on the first stepping motor 5 to work through the PLC control panel 13. The first stepping motor 5 and the chain roller feeding structure 4 send the metal sheet to the lower part of the laser cutting head 8. Subsequently, the double-axis moving module 7 and the laser cutting head 8 are turned on to work through the PLC control panel 13. The double-axis moving module 7 precisely controls the moving trajectory and cutting speed of the laser cutting head 8 on the surface of the workpiece according to the pre-designed cutting path and parameters, realizing high-precision cutting operations. The formed sheet after cutting is located on the chain roller feeding structure 4 and is sent out of the cutting bed by it. The waste material cut from the metal sheet will fall into the U-shaped hopper 2 and be collected by it. When there is a certain amount of waste material in the U-shaped hopper 2 and it needs to be discharged, the staff turns on the horizontal pushing component 9 to work through the PLC control panel 13, so that the horizontal pushing component 9 drives the blocking arm 10 to move in the extending direction of the U-shaped hopper 2, thereby using the blocking arm 10 to push the metal waste material retained in the U-shaped hopper 2 into the receiving hopper 12. When most of the metal waste material is pushed into the receiving hopper 12, the staff then turns on the Y-axis screw linear blanking module 11 to work through the PLC control panel 13. The Y-axis screw linear blanking module 11 drives the receiving hopper 12 to move in the Y-axis direction, so that the receiving hopper 12 moves out of the inside of the cutting bed frame 1, finally realizing the waste discharge function. In this process, the waste material can be directly pushed from the U-shaped hopper 2 into the receiving hopper 12, without the need for operators to clean it manually. In this way, not only the need for manual intervention is reduced, but also the time for cleaning waste is shortened. At the same time, the chance of personnel directly contacting the waste is reduced, the risk of injury is lowered, and it is convenient for the staff to maintain the cutting bed.
